    • A detector oligonucleotide comprises multiple pairs of a donor fluorophore and a quencher molecule, which donor fluorophores and quencher molecules are separated by a site that is capable of being cleaved when in double-stranded form. The detector oligonucleotide may be made double-stranded in a manner that depends on the presence of a target nucleic acid, allowing the cleavage sites to be cleaved. Separation of the donor fluorophores and the quencher molecules decreases fluorescence quenching and generates a detectable change in a fluorescence parameter of the fluorophores of the detector oligonucleotide. By using multiple donor/quencher pairs, the present detector oligonucleotide advantageously generates a high signal to noise ratio and high efficiency in detection of a target nucleic acid.

    • An embodiment of the invention discloses new methods for designing labeled nucleic acid probes and primers by labeling oligonucleotides with a plurality of spectrally identical or similar dyes and optionally with one or more quencher dyes. Oligonucleotides labeled in accordance with some embodiments of the invention exhibit a detectable increase in signal, for example, fluorescent signal when the labeling dyes are separated from one another. Methods for separating the dye include cleaving the labeled oligonucleotides include using enzymes that have 5′-exonuclease activity. In one embodiment nucleic acid primers of the present invention may fluoresce upon hybridization to a target sequence and incorporation into the amplification product. Nucleic acid probes and primers of the present invention have wide applications ranging from general detection of a target nucleic acid sequence to clinical diagnostics. Major advantages of the oligonucleotides including nucleic acid probes and primers of many embodiments of the present invention are their synthetic simplicity, spectral versatility and superior fluorescent signal.

In other embodiments, barcodes may be produced by hybridization of one or more tagged oligonucleotides to a template, comprising a container section and a probe section. The tagged oligonucleotides may be designed as modular code sections, to form different barcodes specific for different targets. In alternative embodiments, barcodes may be prepared by polymerization of monomeric units.
